Chemical/Numerical Exact Matching for Biology

When to use

When a question mentions specific chemical compounds, concentration values (e.g., "0.330 mg/100g"), synonym counts, or other precise numerical data related to a biological species or study.

Technique

Chemical compound concentrations and precise numerical values are extremely strong discriminators in biology searches. Use quotation marks around exact values and compound names. Combining 2-3 chemical names or a compound name + concentration value can uniquely identify a paper or species.

Also leverage synonym counts from taxonomic databases — "5 unaccepted synonyms" combined with a species type can be very distinctive.

Query Templates

• "[chemical compound name]" "[concentration value]" [species name] [method]
• "[compound 1]" "[compound 2]" [species type] edible

Worked Examples

Example

• Question: A species named in the 1780s, 5 unaccepted synonyms, containing specific flavonoid compound concentrations
• Successful query: "Epicatechin" "Catechin" "Amentoflavone" mushroom edible
• Why it worked: Combined chemical compound names (flavonoids) + species type (mushroom) for search, precisely locating Coprinus comatus

Anti-pattern

Not using quotation marks for exact matching when the question provides specific compound concentrations — wasting the strongest discriminator available.
